DEVELOPMENT OF ABRASION ACCELERATING MACHINE OF THE FLOOR FOR REPRODUCING CHANGE OF THE SLIP RESISTANCE FROM ABRASION IN WALKING

The phenomenon rubbed by the heel at the time of walk has effect on change of slip resistance of a floor. The actual abrasion experiment rubbed by the heel was conducted. As a result, the abrasion sample was able to be obtained and change of slip resistance has been grasped. The accelerating abrasion machine of the floor which gives the abrasion load by the phenomenon to rub was developed. With the developed accelerating abrasion machine, change of the slip resistance obtained in the actual abrasion experiment is reproducible.
